FORWARD-LOOKING STATEMENTS

This press release contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended,

including statements relating to SIGA’s future business development and plans. Forward-looking statements include statements regarding our future financial position, business strategy, budgets, projected costs, plans and objectives of management

for future operations, and delivering products to domestic and international customers under procurement contracts. The words “may,” “continue,” “estimate,” “intend,” “plan,” “will,” “believe,” “project,” “expect,” “seek,” “anticipate,” “could,”

“should,” “target,” “goal,” “potential” and similar expressions may identify forward-looking statements, but the absence of these words does not necessarily mean that a statement is not forward-looking. Such forward-looking statements are subject

to various known and unknown risks and uncertainties, and SIGA cautions you that any forward-looking information provided by or on behalf of SIGA is not a guarantee of future performance. SIGA’s actual results could differ materially from those

anticipated by such forward-looking statements due to a number of factors, some of which are beyond SIGA’s control, including, but not limited to, (i) the risk that SIGA is not able to secure in a timely manner new contracts with the U.S.

Government to substantially maintain or expand the U.S. Government stockpile of TPOXX®, (ii) the risk that SIGA may not complete performance under the 19C BARDA Contract (the "BARDA Contract"), with the U.S. Biomedical Advanced Research and

Development Authority ("BARDA") on schedule or in accordance with contractual terms, (iii) the risk that the nascent international biodefense market does not develop to a degree that allows SIGA to continue to successfully market TPOXX®

internationally, (iv) the risk that potential products, including potential alternative uses or formulations of TPOXX® that appear promising to SIGA or its collaborators, cannot be shown to be efficacious or safe in subsequent pre-clinical or

clinical trials, (v) the risk that target timing for deliveries of product to customers, and the recognition of related revenues, are delayed or adversely impacted by the actions, or inaction, of contract manufacturing organizations, or other

vendors, within the supply chain, or due to coordination activities between the customer and supply chain vendors, (vi) the risk that SIGA or its collaborators will not obtain or maintain appropriate or necessary governmental approvals to market

these or other potential products or uses, (vii) the risk that SIGA may not be able to secure or enforce sufficient legal rights in its products, including intellectual property protection, (viii) the risk that any challenge to SIGA’s patent and

other property rights, if adversely determined, could affect SIGA’s business and, even if determined favorably, could be costly, (ix) the risk that regulatory requirements applicable to SIGA’s products may result in the need for further or

additional testing or documentation that will delay or prevent SIGA from seeking, obtaining or maintaining needed approvals to market these products, (x) the risk that the volatile and competitive nature of the biotechnology industry may hamper

SIGA’s efforts to develop or market its products, (xi) the risk that changes in domestic or foreign economic and market conditions may affect SIGA’s ability to advance its research or may affect its products adversely, (xii) the effect of federal,

state, and foreign regulation, including drug regulation and international trade regulation, on SIGA’s businesses, (xiii) the impacts of significant recent shifts in trade policies, including the imposition of tariffs, retaliatory tariff measures,

and subsequent modifications or suspensions thereof, and market reactions to such policies and resulting trade disputes, (xiv) the risk of disruptions to SIGA’s supply chain for the manufacture of TPOXX®, causing delays in SIGA’s research and

development activities, causing delays or the re-allocation of funding in connection with SIGA’s government contracts, or diverting the attention of government staff overseeing SIGA’s government contracts, (xv) risks associated with actions or

uncertainties surrounding the debt ceiling, or the changes in the U.S. administration, and (xvi) the risk that the U.S. or foreign governments' responses (including inaction) to national or global economic conditions or infectious diseases, are

ineffective and may adversely affect SIGA’s business, as well as the risks and uncertainties included in Item 1A “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2025 and SIGA's subsequent filings with the Securities

and Exchange Commission. SIGA urges investors and security holders to read those documents free of charge at the SEC's website at http://www.sec.gov. All such forward-looking statements are current only as of the date on which such statements were

made. SIGA does not undertake any obligation to update publicly any forward-looking statement to reflect events or circumstances after the date on which any such statement is made or to reflect the occurrence of unanticipated events.
